FALL RIVER — Aaron Hernandez was indicted Thursday on new criminal charges stemming from allegations that he assaulted another inmate at the Bristol County House of Correction and made a threat inside the jail on Nov. 1, 2013.

The Bristol County District Attorney’s Office said it would not comment on the new indictments before Hernandez’s arraignment at a later date in Fall River Superior Court. On Thursday, a Bristol County grand jury indicted Hernandez on charges of assault and battery, and threats to do bodily harm.

Hernandez, 24, is accused of assaulting Andrew Booker, 25, a New Bedford man who was inside the same segregated cell block unit with Hernandez on Feb. 25. Hernandez was outside his cell for one hour of recreation when he allegedly pounced on Booker, who was being transported to the jail’s infirmary, Booker’s lawyer, Michael Maloney, previously said.

Maloney said Booker was handcuffed but alleged that Hernandez was not. Booker was punched and struck several times, and he was on the floor when correctional guards intervened and dragged him by the ankles away from Hernandez, Maloney said.

“It resulted in (Booker) being knocked around quite a bit,” said Maloney, who added that Booker, who is awaiting trial on gun and drug charges, did not want to testify against Hernandez because he did not want to be labeled a rat in jail. Booker has since posted bail.

Bristol County Sheriff Thomas Hodgson said the incident revealed gaps in the jail’s protocols for handling high-profile inmates, who are normally segregated to protect them from other inmates.

Hodgson said new protocols require all inmates in the segregated unit — including those outside their cells on recreation — to be locked inside their cells while another inmate is being moved.

Hodgson confirmed that Hernandez is accused of threatening a jail correctional officer and his family last November.

The sheriff declined to release further details about the alleged threats. Hodgson said the jail investigated the allegation and found that it warranted a “further review.”

“Anytime there is an allegation that someone in our custody threatens somebody else, whether it’s another inmate, a correctional officer or staff member, we take that very seriously," Hodgson said.

Hernandez has been moved to a different cell block in the jail, though he is still in special management, and allowed to be outside his cell only when no other inmates are out of their cells.

Hernandez, the former Patriots tight end, is already facing murder and firearms charges stemming from the June 2013 slaying of 27-year-old Odin Lloyd in North Attleborough. Prosecutors allege Hernandez orchestrated Lloyd’s homicide after a disagreement the two men had two nights earlier at a Boston nightclub. Hernandez’s two alleged co-conspirators, Carlos Ortiz, 27, of Bristol Conn., and Ernest Wallace, 45, of Miramar, Fla., were recently indicted on murder charges after having been charged as alleged accessories after the fact. They will be arraigned on the new charges at a later date in Fall River Superior Court.
